(a) During the car speed significantly more than 20 miles per hour, any wheel to your an effective nonsteerable shaft aside from both rearmost nonliftable, nonsteerable axles will get lock up, when it comes down to period. 3.1(b).

(b) On vehicles rate more than 20 miles per hour, you to wheel on the one axle otherwise a couple wheels on people tandem will get lock up for the years.

(c) From the vehicle speed significantly more than 20 miles per hour, people controls maybe not permitted to protect 3.step one (a) or (b) will get lock up several times, with every lockup occurring to own a length of one next or smaller.

A vehicle appointed in order to tow various other auto equipped with air brake system will meet the a lot more than launch day requirements that have a good 50-cubic-inches shot reservoir connected to the handle range production coupling

3.step one.1 Avoid the car out-of sixty mph toward a body with a peak rubbing coefficient out-of 0.9 with the vehicles piled the following:

(a) Loaded in order to their GVWR so that the weight for each shaft, counted in the tire-surface screen, is really almost proportional into the axles’ respective GAWRs, versus exceeding the fresh GAWR of every axle.

S5

(b) On the truck tractor just arrangement in addition to up to five hundred lbs. or, at the maker’s choice, from the its unloaded lbs along with around 500 lbs. (and driver and you will instrumentation) and you will and additionally not more than an additional step 1,000 lbs. to own a roll pub structure into vehicle, and you will

(c) During the its unloaded vehicle lbs (with the exception of vehicle tractors) including as much as 500 lbs. (also driver and instrumentation) or, at manufacturer’s choice, during the their unloaded pounds and as much as five-hundred lbs. (including driver and instrumentation) together with not more than a supplementary step 1,100 weight. getting a beneficial roll club framework toward automobile. In the event the price attainable in two miles was lower than 60 miles per hour, the car shall avoid out of a performance inside the Table II you to are five to 8 mph lower than the rate attainable in a couple of miles.

3.step 3.1(a) That have a first services tank system heavens stress of 100 psi, the atmosphere pressure into the per braking system chamber shall, whenever mentioned from the first course of services braking system control, arrived at sixty psi during the not more than 0.45 next when it comes to autos and you will vehicles, 0.50 next in the example of trailers, except that trailer converter dollies, built to pull other vehicle equipped with sky brakes, 0.55 2nd regarding trailer converter dollies, and you can 0.sixty second in the case of trailers other than trailers designed so you’re able to tow several other auto armed with air brakes. A motor vehicle made to tow several other vehicle equipped with air brakes should meet with the over actuation date requirements which have an effective 50-cubic-inch take to reservoir connected to the manage range returns coupling. A trailer, including a trailer converter dolly, will meet with the a lot more than actuation big date demands having its manage line input coupling linked to the take to rig shown in the Contour step one.

(b) Getting a vehicle that is designed so you’re able to tow several other vehicles furnished with air brakes, pressure about 50-cubic-inches decide to try tank known inside the 3.step 3.1(a) will, whenever measured on basic course of the solution braking system handle, started to 60 psi perhaps not later on compared to time the fastest braking system chamber on the automobile has reached sixty psi or, at the accessibility to the manufacturer, during the not more than 0.thirty five second in the case of autos and buses, 0.55 second when it comes to truck converter dollies, and you can 0.fifty second regarding trailers other than truck converter dollies.

3.cuatro.1(a) That have an initial services brake chamber sky tension off 95 psi, the atmosphere tension during the for every single braking system chamber shall, whenever mentioned in the very first course of your own solution brake manage, slide to 5 psi into the not more than 0.55 second regarding trucks and you will busses; step 1.00 second when it comes to trailers, other than truck converter dollies, designed to pull some other vehicles armed with air brake system; 1.ten mere seconds regarding truck converter dollies; and you will step 1.20 mere seconds regarding trailers other than trailers tailored to tow some other car equipped with air brakes. A trailer, also a truck converter dolly, should meet the over launch go out requirements using its handle range input coupling attached to the test rig revealed during the Contour 1.
